The effect of impurities and strength level on hydrogen ...

The effect of impurities on the threshold stress intensity for cracking in H 2 S (K{ISCC}) has been investigated at various yield strength levels for a low alloy steel. Results show that the effect of impurities on K ISCC is a function of the yield strength level. At low yield strength levels the K ISCC of the steel is lowered markedly due to additions of impurities.

Effects of Impurity Elements on Green Strength of Powder ...

The green strength of a powder compact results from the mechanical interlocking of the irregularities on the particle surfaces. During compaction, particle rearrangement, plastic deformation and particularly surface deformation of powders occur. Titanium powder is susceptible to interstitial element contamination, which may lead to solid solution strengthening of the particles and/or the ...

Effect of Recurrent Selection for Crushing Strength on ...

Low crushing strength selection decreased crushing strength by 35.3 load-kg per cycle for intact sections and 26.6 load-kg for rind-only sections. Intact section and rind-only weights had similar responses. Rind thickness was altered due to recurrent selection for crushing strength, but the magnitude of change was small and inconsistent.
